Abstract:
The pot experiment was carried out to study the efficiency of combined use of cow
dung and tea waste on seed germination and seedling performance of coriander
(Coriandrum sativum L.) and also study the best ratio of cow dung and tea waste to
seed germination and seedling growth of coriander herbs (Coriandrum sativum L.). It
was laid out in Complete Randomized Design (CRD) with four replications with
following treatments ; T1- 0:0 ratio of cow dung and tea waste as control, T2- 5:0 ratio
of cow dung and tea waste ,T3- 4:1 ratio of cow dung and tea waste, T4- 3:2 ratio of
cow dung and tea waste, T5- 2:3 ratio of cow dung and tea waste,T6- 1:4 ratio of cow
dung and tea waste and T7- 0:5 ratio of cow dung and tea waste.
The results indicated that the efficiency of combined use of cow dung and tea waste
had significant differences (P<0.05) on seed germination, leaf area, fresh and dry
weights of leaves, stem, shoot and root and also root length of young plants but,
number of leaves and shoot length were not significantly efficient due to combined use
of cow dung and tea waste.
According to that statistically analyzed result, combined use of cow dung and tea waste
4:1 ratio (T3),5:0 ratio (T2),3:2 ratio (T4) and 0:5 ratio (T7) showed significant
difference with 0:0 ratio (T1) in different seedling performances. In fresh leaves
weight T2,T3 and T4 were showed significant difference with T1. In root length T2
and T7 were showed significant difference with T1, but only T7 was showed
significant difference with T1 in dry root weight. T2 and T4 both treatments were
showed significant difference in seed germination % and seedling performances such
as fresh leaves weight. fresh shoot weight with T1.T2 was showed significant
difference with T1 in fresh root weight and dry leaf weight, but T4 was showed
significant difference with T1 in seed germination % and seedling performances such
as leaf area, fresh stem weight, dry stem weight and dry shoot weight. According to
that results, T4 was showed greater times seedling performances than other treatments.
Cow dung and tea waste are the most readily available organic manure for enhancing
seed germination and seedling performance of coriander. As a result, cow dung and
tea waste at 3:2 could be utilized to increase seed germination and seedling growth to
coriander herbs.
